BACKGROUND INFORMATION

1. Field of the Disclosure

The present invention relates generally to systems and methods for optimizing shopping techniques. In particular, assisting a user with an electronic shopping list on a mobile computing device optimize their shopping experience by determining product waypoints corresponding to the items contained in the electronic shopping list.

2. Background

Many consumers visit supermarkets and superstores when shopping for products such as groceries, office supplies, and household wares. Typically, these stores can have dozens of aisles and/or sections. Accordingly, traversing these aisles looking for specific products may be a harrowing experience. Situations may arise where a consumer takes a brute force approach to shopping for products, where the consumer crosses the store multiple times to find all the intended products. Consumers may use a digital shopping list in order to better organize and remember their items when preparing to go shopping. The shopping list alone, however, may not be the complete solution to the problem of repeatedly crossing aisles during shopping or visiting the same regions of the stores multiple times.

The digital photograph can be a bitmap file. The bitmap file can be a bitmap, a JPEG, a GIF, or any other suitably formatted file. The camera 108 can receive the instruction to capture the image from the processing device 100 and can output the digital photograph to the processing device 100.

The shopping list generation module 110 allows a user to generate an electronic shopping list and displays the electronic shopping list to the user in the GUI 12 (FIG. 1) via the user interface 102. As discussed previously the shopping list generation module 110 may be configured to generate the electronic shopping list based on items manually entered by the user, a photograph of a handwritten shopping list, previous electronic shopping lists of the user and/or a purchase history of the user. It is appreciated that the shopping list generation module 110 can generate the electronic shopping list in any other suitable manner.

The shopping assistance module 112 assists the user when preparing to shop for the items in the electronic shopping list. The shopping assistance module 112 can be configured to determine a store location indicating the store at which the user intends to purchase the products indicated in the electronic shopping list. The store location can be represented in GPS coordinates of the store or by a store identifier, e.g., an alphanumeric string that identifies the store from other stores. In some embodiments, the shopping assistance module 112 uses the current location of the mobile computing device 10 to determine the store location. For instance, if a retailer operates three different stores in the vicinity of the mobile computing device 10, the shopping assistance module 112 can select the nearest store as the store location. The store locations can be obtained from a remote server, e.g., the shopping list server 30, and/or can be stored on the memory device 106 of the mobile computing device 10. In some embodiments, the shopping assistance module 112 allows the user to select the store location from a plurality of different store locations. For example, the shopping assistance module 112 can display a drop down menu in the GUI 12 that allows the user to select the store location. In these embodiments, the shopping assistance module 112 may instruct the user to provide a postal zip code and/or a city and state of the user. Using this information, the shopping assistance module 112 can display the N nearest store locations, where N is an integer greater than or equal to one. Alternatively, the shopping assistance module 112 can learn the user's preferred store location or can store the user's preferred store location. It should be appreciated that the shopping assistance module 112 may determine the store location in any other suitable manner.

In some embodiments, the shopping assistance module 112 determines the product waypoints for the items in the electronic shopping list. In some of these embodiments, the shopping assistance module 112 provides the electronic shopping list, or the items contained therein, and the store location to the shopping list server 30. The shopping list server 30 can return the product waypoints corresponding to the items contained in the electronic shopping list to the shopping assistance module 112. The shopping assistance module 112 can display the product waypoints to the user. In this way, the user may view the product waypoints when shopping to more efficiently locate the products indicated in the electronic shopping list when shopping.

In some embodiments, each product waypoint may be displayed in the electronic shopping list relative to its corresponding item. For example, FIG. 3 illustrates an example of an electronic shopping list that has product waypoints displayed in relation to their corresponding items. In the illustrated example, the electronic shopping list is displayed on the left-hand side of the GUI 12. On the right-hand side, the product waypoints corresponding to each item are illustrated. As can be appreciated, the product waypoints can identify a specific aisle if the product indicated by the item is in an aisle. Otherwise, a description of the section of the product, e.g., “Produce” or “Sunglasses,” can be used to show the location of the product. It is noted that the example of FIG. 3 is provided for example only and not intended to be limiting.

In some embodiments, the shopping list server 30 may also return a map corresponding to the store location. As used herein, the term “map” may refer to a digital representation of the layout of the corresponding store location. Referring to FIG. 4, an example of a map 150 having a plurality of product waypoints displayed therein is illustrated. The shopping assistance module 112 can display the map 150 to the user via the user interface 102 (FIG. 2). In the illustrated example, the product waypoints are displayed as graphical icons, e.g., stars. For example, the map 150 includes a first product waypoint 152 (e.g., location of “milk”) and a second product waypoint 154 (e.g., location of “cheese”) in the dairy section. Additionally, the map 150 includes a third product waypoint 156 (e.g., location of “lettuce”) in the produce section, a fourth product waypoint 158 (e.g., location of “curtains”) in the home decor department, a fifth product waypoint 160 (e.g., location of “sunglasses”) in the kids clothing department, and a sixth product waypoint 162 (e.g., location of “HALLMARK® card”) in the cards/stationary department. Furthermore, the map 150 includes a seventh waypoint 164 (e.g., location of “ice cream”) in the frozen goods section. As can be appreciated, the graphical icon used to represent the seventh waypoint 164 is a pair of bold lines, thereby indicating that the both sides of aisle 14 contain ice cream.

In some embodiments, the graphical icons representing the product waypoints can be displayed in the map 150 in varying sizes to indicate to the user the relative amount of space that is occupied by the product indicated in the electronic shopping list. For example, the product referenced by the first product waypoint 152 may represent the location of “cheese” while the product referenced by the second product waypoint 154 represent the location of “milk.” As can be appreciated by the respective sizes of the first product waypoint 152 and the second product waypoint 154 in this example, the amount of space occupied by milk is greater than the amount of space occupied by cheese.

Furthermore, in some embodiments, the map may also display an entrance waypoint 168 and/or a checkout waypoint 166. The entrance waypoint 168 may indicate a suggested entrance for the user to enter/exit from. The checkout waypoint 166 may indicate one or more suggested checkout lanes at which the user can checkout. As will be discussed in greater detail below, the entrance waypoint 168 and the checkout waypoint 166 can be determined based on the items in the electronic shopping list.

It is noted that in some embodiments, the shopping assistance module 112 can be configured to receive the map 150 and the various waypoints 152-168, and to render the map 150 with the waypoints 152-168 displayed therein. In other embodiments, the shopping list server 30 may be configured to render the various waypoints 152-168 in the map 150 and to provide the rendered map 150 to the shopping assistance module 112.

In some embodiments, the shopping assistance module 112 can utilize the current location of the user to display the current location of the user in the map 150 while the user is shopping. In this way, the user can reference his or her location in relation to the various waypoints 152-168 to better navigate through the store. It is noted that the example map 150 of FIG. 4 is provided for example and not intended to be limiting.

Referring back to FIG. 2, in some embodiments the shopping assistance module 112 is configured to determine an optimized route for the shopper to travel when shopping for the products indicated in the electronic shopping list. In some of these embodiments, the shopping assistance module 112 provides the electronic shopping list, or the items contained therein, and the store location to the shopping list server 30. The shopping list server 30 can return a route corresponding to the items contained in the electronic shopping list to the shopping assistance module 112. In some embodiments, the route can be optimized, for example, to minimize a distance traveled through the store or to minimize an amount of time spent traveling through the store. The shopping list server 30 may further return the product waypoints corresponding to the items contained in the electronic shopping list.

In some embodiments, the shopping assistance module 112 can display the route to the user in a map. FIG. 5 illustrates an example of a map 150 having a route 170 displayed therein. The example map 150 of FIG. 5 builds upon the example map 150 of FIG. 4. Accordingly, objects appearing in FIG. 5, which were discussed in FIG. 4 are referenced using the same reference numerals. In the illustrated example, the route 170 begins at the entrance waypoint 168 and travels through the first waypoint 152, the second waypoint 154, the third waypoint 156, the fourth waypoint 158, the seventh waypoint 165, the fifth waypoint 160, the sixth waypoint 162, and the cashier waypoint 166.

It is noted that in some embodiments, the shopping assistance module 112 can be configured to receive the map 150, the various waypoints 152-168, and the route 170 and to render the route 170 and the waypoints 152-168. In other embodiments, the shopping list server 30 may be configured to render the route 170 and the various waypoints 152-168 in the map 150 and to provide the rendered map 150 to the shopping assistance module 112. In some embodiments, the shopping assistance module 112 can utilize the current location of the user to display the current location of the user in the map 150 while the user is shopping. In this way, the user can reference his or her location in relation to the route 170 to better navigate through the store. It is noted that the example map 150 of FIG. 5 is provided for example and not intended to be limiting.

Referring back to FIG. 2, in some embodiments the shopping assistance module 112 is configured to rearrange and/or group the items in the electronic shopping list, such that the items are rearranged or grouped in a manner to increase the efficiency of the user's shopping experience. For example, in some embodiments the items can be rearranged according to the respective locations of the products indicated by the items. In these embodiments, the items can be rearranged such that the items are displayed in an order that corresponds to the respective distance between other items. For example, in the electronic shopping list of FIG. 1, “curtains” are listed after “HALLMARK® card”. Assuming that curtains are in the home decor department and HALLMARK® cards are located in the stationary department, the items may be rearranged in the electronic shopping list such that the “HALLMARK® card” is displayed directly before or after sunglasses, while “curtains” is displayed after lettuce and before ice cream.

In other embodiments, the items can be grouped according to the types of the products indicated in the electronic shopping list and/or the respective sections/departments of the products indicated in the electronic shopping list. Referring to FIG. 6, an example of an ordered electronic shopping list is illustrated. In the example, the electronic shopping list of FIG. 1 has been rearranged and grouped according to product type. For example, the ordered electronic shopping list includes a “groceries” grouping 180, a home decor grouping 182, and a personal items grouping 184. Furthermore, within the groupings, the ordered electronic shopping list may be grouped according to section/department. For example, the “cheese” item 188 and the “milk” item 190 have been grouped in a “dairy” grouping 186. As can be appreciated, the “dairy” grouping 186 is indicative of the section of the store where cheese and milk can be found. The example of FIG. 6 is provided for illustrative purposes and not intended to be limiting. The items appearing in the ordered shopping list can be grouped according to any other suitable categories.

As referenced above, the shopping list server 30 may be configured to perform one or more functions at the request of the mobile computing device 10. FIG. 7 illustrates an example embodiment of the shopping list server 30 configured to perform one or more of the requested functions. In the illustrated embodiment, the shopping list server 30 may include a processing device 300, a communication device 304, and memory device 306.

The processing device 300 can include memory, e.g., read only memory (ROM) and random access memory (RAM), storing processor-executable instructions and one or more processors that execute the processor-executable instructions. In embodiments where the processing device 300 includes two or more processors, the processors can operate in a parallel or distributed manner. In the illustrative embodiment, the processing device 300 executes one or more of a store locator module 310, a product locator module 312, a route determination module 314, and a grouping module 316.

The communication device 304 is a device that allows the shopping list server 30 to communicate with another device, e.g., the mobile computing device 10, via the network 20. The communication device 304 can include one or more wireless transceivers for performing wireless communication and/or one or more communication ports for performing wired communication.

The memory device 306 is a device that stores data generated or received by the shopping list server 30. The memory device 306 can include, but is not limited to a hard disc drive, an optical disc drive, and/or a flash memory drive. Further, the memory device 306 may be distributed and located at multiple locations. The memory device 306 is accessible to the processing device 300. In some embodiments, the memory device 306 stores a store location database 320 and a product location database 322.

In some embodiments, the store location database 320 can store the store locations of one or more stores operated or associated with a retailer. The store location database 320 may be queried using a specific location, e.g., GPS coordinates, or a general location, e.g., postal zip code or city/state, and can return one or more stores that are proximate to the specific or general location. The store location database 320 may further be configured to store maps corresponding to each store location. The store location database 320 may be queried with a store location and can return the store map corresponding to the store location.

In some embodiments, the product location database 322 stores product waypoints indicating locations of the products sold by a retailer in the one or more stores operated or associated with the retailer. For example, the product location database 322 may store the location of “milk” in each of the stores operated or associated with the retailer. The product location database 322 may be queried with the item “milk” and a specific store location, and may return a waypoint indicating the location of “milk” at the specific store location.

The product location database 322 may be configured to store waypoints for specific products and generic products. For example, the product location database 322 may be configured to store waypoints indicating the location of “ice cream,” a generic product, and the location of “BEN AND JERRY'S® ice cream,” a specific product. It should be noted that a waypoint corresponding to a generic product or specific product may be represented using a starting location and ending location. For example, a waypoint corresponding to “ice cream” may indicate where the ice cream section begins and where the “ice cream” section ends. Similarly, a waypoint corresponding to “BEN AND JERRY'S® ice cream” may indicate where the BEN AND JERRY'S® ice cream begins and ends. It should be appreciated that when a specific product is a species of a generic product, e.g., BEN AND JERRY'S® ice cream is a species of “ice cream,” the waypoint corresponding to a specific product may be wholly contained within the waypoint corresponding to the generic product. In some embodiments, a generic product may be located in more than one location in the store. For example, milk may be located in the dairy section, while organic milk may be located in the natural foods location. In this type of scenario, the product location database 322 may store more than one location for milk. When such a situation arises, the product locator module 312 may retrieve multiple product waypoints, such that the multiple waypoints corresponding to the generic product are provided to the mobile computing device 10.

The product location database 322 may further store a type of each product sold by the retailer, e.g., groceries, home decor, and personal goods, and/or a section of the product, e.g., dairy or men's clothing. Furthermore, the types and/or sections can be stored relative to each store location. In this way, the product location database 322 can be queried with a store location and a product and can return a type of the product and/or a section of the product at the store location.

As discussed, the processing device 300 may execute the store locator module 310. The store locator module 310 receives a location from the mobile computing device 10 and determines one or more store locations corresponding to the received location. In some embodiments, the store locator module 310 queries the store location database 320 with the received location and receives one or more store locations that correspond to the received location. For example, the store location database 320 may return any store locations that are within a predetermined distance, e.g., 10 miles, from the received location. When more than one store location is received, the store locator module 310 may automatically select the store location nearest to the received location or may provide the store locations to the mobile computing device 10, thereby allowing the mobile computing device 10 or the user to select the store location.
